New Zealand mosque attack: 'Let's get this party started' boasted Brenton Tarrant

In the wake of a terror attack on two Christchurch mosques that took the lives of 49 people and injured at least 20, people have been expressing their sympathies for the victims by leaving flowers at local mosques in New Zealand and around the world.

The 59-year-old Canadian songwriter was due to appear at Hagley Park in the New Zealand city on Sunday, but has since put the concert on hold following the tragic attack. David Gray went on a rampage, killing 12 people, including four children and a police officer.

Law enforcement officials in other cities across the country, including NY and Los Angeles, have also said they are increasing security forces at mosques in response to the shooting. One person has been arrested and charged with murder.

Law enforcement sources have told CBS News that Australian-born Brenton Harrison Tarrant, 28, was charged with murder over the attacks on the two mosques.
